I remember the first time I met my step sister, we played toys together and she excused herself to the bathroom, which was right next to her bedroom. I was only like six or seven but I put my ear up to the wall to hear her using the toilet
Another memory off the top of my head, was the time this one geeky girl who was always really clingy with me until I told her to fuck off was out on the football field with me (this was like 7th grade or something) and she farted, so to cover up the fart she slipped and fell on the wet grass to make it seem like the fart that happened one second earlier was.. the grass? Anyhow she fell on her ass and got all dirty lol.
